The helicopter will lift logs cut during a project to reduce the dangers of wildfire and improve forest health. Crews started the logging last week.

Ashland residents will be able to hear the helicopter during the work, officials said.

Trails will be closed during the work. Affected trails in the area include the upper Alice in Wonderland, White Rabbit, Caterpillar, Jabberwocky, Toothpick, Marty's, Catwalk and Eastview trails. Access to the Ashland Loop Road is closed above Morton Street and at U.S. Forest Service Road 2060-500. The Toothpick Trail area near Upper Tolman Creek Road and Forest Road 2080, which includes the Four Corners trailhead, is closed.

Signs will be posted on closed trails and roads, and will be in effect seven days a week. All areas should reopen by May 1, officials said.
